of the United States of America, residing at Baltimore, in the State of Maryland, has invented new and useful Improvements in Shoes, of which the following is a specifi- The object of the invention is to provide a construction of shoe and method of producing the same whereby a relatively inferior grade of leather may be'utilized as the material for the insole, whilemaintain 111g a high standard of the product in the matter of strength, durability, retention or permanence of shape in the shoe and like qualities or characteristics ordinarily obtainable only byuse of a superior grade of insole and, therefore, to efiect an economy in the consumption of hides by: affording a primary use for the larger percentage of the area of each hide in the production of standard grades of shoes and minimizing the waste or rejection of the major portion of each hide, as in the present practice, except in connection with or forthe manufacture of goods which cannot be consistently handled by reputable dealers as first line or high quality goods.

It is a well recognized fact, among manufacturers and dealers that the portion of a hide which can be used in the formation of insoles for high grade or expensive shoes and boots is limited in area, and while other por tions are employed for that purpose they are introduced into second or lower grades of shoes and are open to the objection that by reason of lacking in strength and stability, and the property of maintaining, the originalshape, the shoe in which the same isii'icorporated becomes distorted owing to the stretching and warping of the insole, and in addition thereto these lower grade portions of the hide being thinner than the pre-' ferred portions are reduced to such an extent by the channelling as to render the insole liable to breakage or separation betweenthe web end and the insole proper, with the result obviously that the edge of the'upper is released and patching is necessary'in ord'er to preserve the shoe. As aniatter of fact,

it occasionally happens that the stitching of the upper to the web in the manufacture of the shoe involves the cutting or breaking of thefweb at its joint with the body ofthe insole so that the article must be rejected or a patch must be applied "to retain the de tached portion of the web in Be it known that MEYER S. Hnss, a QltlZell' tion to provide j its proper position, with the nevitable result that a damaged, 1nfer1or grade of product is the result.

It 1s, therefore, the object of this invenmeans'whereby the web of an insole constructed of a relatively low or inferior grade of leather not having thickness, strength and stability of the higher grade may be reinforced in order to withstand the effect of applying stitches bv which the upper is secured thereto and to successfully carry the strains incidentto the use ofthe shoe tothe end that a durability practically the equivalent of that secured through the use of the higher grade of leather, may be secured without adding materlally to the cost of manufacture or the procedure incident to the construction of the shoe; and in this connection to provide a construction, combination and relation of parts, of which preferred embodiments are llustrated in the accompanying drawings, it being understood that changes in form, proportion and details may be resorted to within the scope of the appended claims without detracting from the principles involved. r

In the drawings:

Figure 1, is'a cross sectional view of the vamp portion of a shoe embodying an insole constructed in accordance with the in Fig. 4, is a view similar to Fig. 3 showing the welt and upper in place secured by stitching.

Fig. 5.,is a plan view of a portion of an insole embodying a slightly modified arrangement cf the reinforcing element.

Fig. .6, is an enlarged cross sectional view of the construction shown in Fig. 5.

Fig. 7, is a plan view showing another modified arrangement of the reinforcing element. 7 i I i Fig. 8, is an'enlarged sectional View of the construction shown in Fig. 7. V

In the preparation of an insole for incorporation in a shoe, the usual practice is followed in so far as'the channeling or grooving of the body of the insole shown at 10 forming the feather edge 11 and the upstanding web or lip consisting of the inner and outer elements 12 and 13 through which angle formed between the lip and the body portion of the insole, and it is on this line, where the leather of the insole is deflected from the plane of the insole to form the web or lip, that the liability of cutting or breaking the material and the weakening of the structure occurs and it is to prevent such an injury and detraction from thestrength of the ultimate product that it is proposed to reinforce the web or lip in its relation to the body portion of the insole by applying a. reinforcing strip 19 of suitable fabric spanning the angle formed between the web or lip and the surface of the insole and adhesively secured to the surface of the web and the insole.

In the construction illustrated, the reinforcing strip which may be of canvas or like material is of just su'llicient width to obtain a substantial bearing upon the surface of the insole parallel with the inner surfaces of the web or lip, and in order to facilitate the adhesive attachment of the same to the surface of the insole and the web or lip, the

strip may be initially rubberized or coated with an adhesive material and may be supplied, for example, in a continuous length to the worlnnan to be applied to the insoles successively as they pass through his hands after the preliminary channeling or grooving as above suggested.

Moreover in applying the reinforcing strip to the insoles, it is preferable to secure the edges thereof respectively to the web and the surface of the body portion of the insole so as to truncate the angle formed by the said surfaces as indicated in Fig. v 8, to the end that when the stitching is applied to attach the upper to the insole, the loose or truncating portion of the reinforcing strip will be drawn into or toward the angle between the surfaces of the web or insole and vill tension the strip and consequently proportionately strengthen or stabilize the web.

in the construction illustrated in Figs. 1 to l; inclusive, the reinforcing strip is doubled upon itself to overlap or extend over the upper edge of the inner member of the web or lip with the inwardly extending flap or edge 20 thereof adhesively secured to the exterior surface of said member as the body portion of the strip is adhesively secured to the interior surface of the web member, after which, in the combining of the elements of the shoe, stitches which attach the upper to the web or lip pass not only through the body portion of the strip from the inside of the web or lip, but also pass through the inwardly turned or doubled edge 20 of said strip and through the outer member of the web or lip as indicated in Fig. 4, the in-turned edge or portion 20 of the reinforcing strip thus being embraced by or clamped between the inner andouter members of the web or lip.

Obviously any strain applied to the upper or welt will be. resisted not only by the strength of the material forming the insole and web or lip, but the tensile strength of the reinforcing strip, to the end that the breaking away of the web or lip or any portion thereof from the body of the insole or the distortion of the said web or lip, will be prevented even though the insole may be made of a relatively thin portion of the hide. Obviously when the outer channel or groove is formed of a varying width as in the ordinary practice, tending to provide an outer web or lip member which varies in projection from the plane of the body portion of the insole, the surplus edge thereof may be trimmed to secure correspondence in height between the inner and outer web or lip members, either before or after the application of the reinforcing strip as above described. I

In the modified construction shown in Figs. 5 and 6, the reinforcing strip 22 corresponcs substantially with that above de scrioed except that in its application to the web or lip, consisting of the inner and outer elements 23 and 24, the outer reversed edge thereof is adhesively secured to the outer surface of the outer element of the web or lip, so that the strip embraces both members orelements of the web or lip, the adjacent surfaces of the latter being adhesively secured together. In this construction also the reinforcing strip overlaps the upper edge of the web or lip and the line of stitching by which the upper is attached to the insole may pass through both the inner and outer folds of the strip as well as through the web or lip.

In the further modified construction illus t ated in Figs. 7 and 8, the reinforcing strip 26 is arranged and secured as hereinbefore described except that it terminates at or about flush with the upper edge of the web or lip 27 of which themembers or elements are adhesively secured together (if preferred) instead of overlapping and having a reverse or return extension for contact with the exterior surface of the web or lip as in the forms previously described. In all of the illustrated forms, however, the ame procedureis followed in reference to the adhesive securing of the reinforcing strip to the surface of the web or 'lip and the insole proper in spanning relation with the angle formed thereby or between the same, to guard against the tendency of the web or lip by reason of any inferiority or weakness of the material, to break or separate at the bend or deflection forming said angle, and in order to adapt the strip to accurately follow the curvature of the web or lip, the inner edge thereof is preferably scalloped as shown at 28.

The invention having been described, what is claimed as new and useful is 1. A shoe insole having in connection with its web or lip a reinforcing strip marginally attached to the web and the adjacent surface of the insole in spanning relation with the inner angle formed thereby for tensioning by the uppersecuring stitches. 2. A shoe insole having in connection with its web orlip,a reinforcing fabric strip marginally attached at its edges to theweb and the adjacent surface of the insole in spanning and truncating relation with the inner angle formed thereby for tucking and tensioning by the upper securing stitches.

3. A shoe insole having in connection with its web or lip a reinforcing strip adhesively attached marginally to the web and the adjacent surface of the insole in spanning and truncating relation with the inner angle formed thereby for tensioning by the uppersecuring stitches intersecting said web and strip.

4. A shoe insole having in connection with its web, a reinforcing strip adhesively attached marginally to the inner surface of the web and the adjacent surface of the insole in spanning relation with the angle formed thereby.

5. A shoe insole having in connection with its web a reinforcingstrip attached marginally to the inner surface of the web and the adjacent surface of the insole in spanning tensionable relation with the angle formed thereby, said strip overlapping the free edge of the web.

6. A shoe insole having in connection with its web, a reinforcing strip attached marginally to the inner surface of the web and the adjacent surface of the insole in spanning tensionable relation with the angle formed thereby, said strip overlapping the free edge of the web and being reversely extended in parallelism therewith into the zone of the upper-attaching stitches for engagement thereby.

7. A shoe insole having in connection with its web, a reinforcing strip adhesively attached to the inner surface of the web and the adjacent surface of the insole in spanning and truncating relation with the angle formed thereby, said strip overlapping the free edge of the web, and being reversely extended at its upper edge toward the plane of the insole.

'8. A shoe insole having in connection with its web or lip, a reinforcing strip attached adhesively to the inner surface of the web and the adjacent surface of the insole in spanning and truncating relation with the angle formed thereby, the outer edge of the strip being doubled upon itself to embrace the web.

9. A shoe insole having in connection with a composite web of inner and outer elements, a reinforcing fabric strip marginally attached to the surface of one element and the adjacent surface of the insole inwardly of the web, in spanning relation with the angle formed thereby. v f

10. A shoe insole having in connection with its web or lip composed of inner and outer elements, a reinforcing fabric strip embracing'the inner web or lip element and adhesively attached thereto and to the adjecent portion of the surface of the insole in spanning relation with the inner angle formed thereby.

11. A shoe insole having outer and inner up-turned web or lip elements and a reinforcingfabric strip disposed in parallelism with said elements, adhesively secured to the surface of the body portion of the insole and embracing and adhesively secured to the opposite surfaces. of the web. or lip.

12. A method of forming a shoe insole which consists in channeling or grooving the same to produce inner and outer web or lip elements and adhesively attaching a reinforcing strip to adjacent surfaces of the web or lip and insole in spanning relation with the angle therebetween in the zone of the upper-attaching stitches.

13. The method of forming a shoe insole which consists in channeling or grooving the same to produce a web or lip and adhesively attaching a reinforcing strip to adjacent surfaces of the web or lip and the insole in spanning and truncating relation with the angle therebetween and in the path of the upper-attaching stitches.

In testimony whereof I afiix my sig-' nature.
